Blood plasma

July 16 (Bloomberg) — CSL Ltd. and Baxter International Inc. were sued by a Missouri hospital over allegations they conspired to fix and raise prices for blood plasma products.

The companies used key words to encourage each other to increase supply only incrementally to keep pace with demand and not to increase supply to the extent the companies actually compete for market share, lawyers for Pemiscot Memorial Hospital, based in Hayti, Missouri, said in a complaint filed yesterday. The lawsuit was filed in Philadelphia federal court.

“As a result of the conspiracy, prices for blood plasma products were higher than they otherwise would have been,” Marc Machiz, an attorney for Pemiscot, said in the complaint. “Beginning in 2005 and continuing through the present, prices for blood plasma proteins have increased substantially.”

Baxter and Melbourne-based CSL are the world’s largest makers of blood plasma products. Last month CSL abandoned a $3.1 billion bid for Talecris Biotherapeutics Holdings Corp. after regulators blocked the plan.
